That's been sitting in a browser tab for a week or two because I'm not sure if "culture" only applies to bacteria or if the term is applicable to a wide variety of microbiologic techniques. But I suppose it's close enough for a pun.

"Culture" is absolutely the right word -- Stem cell culture is a potentially less morally-debatable process of acquiring stem cells that is currently being developed and researched, to see if stem cells can be lab-grown, i.e. cultured.
